My "beast" was a 1981 Suzuki GS650EX. Cafe fairing, narrow straight bars, Yoshimura headers & pipe.
That had an "on/off" instead of a throttle. At least the way I rode it. Yippee!!
Was only a matter of time until I killed myself, and I sold it after one almost. I lost it on gravel and the bike went into a culvert. I kept going and skidded 60 feet on my back (over grass - thankfully). A nice tree stopped me and smashed my Simpson full-face helmet. My then two-years newlywedded wife pleaded with me to sell it, so I replaced the damaged parts and did. I miss it every spring.
